Dayco Curved Radiator Hose 72312

Dayco 72312 is a curved radiator coolant hose built from EPDM for reliable coolant transfer in the engine cooling system. It uses a single I.D. hose design with a 1 11/32 in. inside diameter at both ends and a black finish for a direct-fit replacement on select Hyundai and Kia applications.

Key Features

  • EPDM construction for coolant hose service
  • Single I.D. hose with 1 11/32 in. inside diameter at both ends
  • Curved radiator hose profile for lower cooling-system routing
  • Black exterior finish
  • Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Dayco Curved Radiator Hose line for OE-style cooling system replacement

Product Details

This Dayco Curved Radiator Hose is engineered for lower radiator hose service where a formed hose shape is required to follow the factory coolant path. The EPDM rubber construction is suited for hot coolant exposure, while the curved profile helps maintain proper routing in the cooling system. Dayco 72312 is a direct replacement choice for 2005-2010 Kia Sportage lower hose applications and 2005-2009 Hyundai Tucson lower hose applications. This part cross-references Gates 23063 for the same application.

Vehicle Fitment

  • Fits 2005-2010 Kia Sportage, Lower
  • Fits 2005-2009 Hyundai Tucson, Lower

Common Uses

  • Replacing a cracked or aging lower radiator hose
  • Restoring coolant flow after hose swelling or softening
  • Correcting coolant leaks at the lower hose connection points
  • Replacing a hose that no longer holds its formed curve
  • Servicing cooling-system maintenance on Hyundai Tucson and Kia Sportage models

Installation Notes

Verify hose routing, end diameters, and lower-position fitment before installation. Inspect the mating necks, clamps, and adjacent cooling-system components for wear or corrosion, and confirm the hose follows the factory curve without twisting. Dayco 72312 should be installed on the specified lower radiator hose application for the listed Hyundai Tucson and Kia Sportage vehicles.

Quality Assurance

This hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for radiator coolant hose service.
